apps2sd+: Why exactly is the /data/data not moved to the SD?

[Guest BDrift]

... I'm just curious about it, because of all the "apps2sd still eating some internal memory"-topics.

I just moved everything in /data/data to a directory on the sd card and linked it to the empty /data/data directory and it worked perfectly fine. I installed ~130MB worth of apps and the internal memory still showed up with 144MB beeing free.

After a reboot the symbolic link (mount --bind) was gone of course ... but why doesn't apps2sd set it up like that in the first place?

edit:

My guess would be it has something to do with HTCs own basic apps which all seem to live within the /data/data folder? Might become a problem if you replace the sdcard (for whatever reason) ... but shouldn't there be a workaround or something?

/data/data moved to sd right after wipe

40 apps later:

How did you link the folders? I have root explorer and see no option for it in there... i also run win 7 x64. Can I do it via a different app or within win7?

It will be really great if /data/data can be moved to the sd card as well. Quite alot of data for the apps are being stored there. Google Earth for example, 17MB went into /data/data and only 5MB+ went to the sd card.

Read this post here. It is mentioned that moving /data/data to the sd card will cause instability and lots of issues.

@myth1001 thanks m8 - just the info I was looking for :D Hopefully it'll be sortet out some time.

@Emperork: It's just a symlink I created via adb shell. No big magic there :rolleyes: Lets just wait for the pro's to fix the apps2sd stuff.

And how do you create that link? :s what command?

is it just "adb symlink /data/data /system/sd or something like that? :(

Thx

In linux just type ln -s [source name] [linkname]

example:

ln -s /sdcard/dir_where_you_wanna_store_data data_link

i think you can use ln command from better terminal directly from your phone without adb shell from your pc

[Guest kendon]

1. why would you want to this? is there really not enough space in /data for only userdata?

2. you might wanna link it to a folder on the ext (apps2sd) partition of the sdcard, the fat32 doesn't support proper unix style permissions and will therefore most likely mess up your system.

Oh man, Ubuntu still manages to look unbelievibly awesome even on a screenshot.

so i move the /data/data folder to the sdcard, en then link it, or do i just use ln -s and it will be moved and linked? :s

move the data and then create the link, but i wouldn't do it because ppl in the forum say that can cause system instability...

Ok thx

Won't do it yet, but it's a nice backup plan if I really run out of data ^^

But I was wondering, if the link get's removed on boot, will it be able to startup decent? :(

Yes it'll be removed after a reboot and your phone would be messed up (at least all the apps you installed would probably crash ... eventually some of htc's apps as well).

You would have to reestablish the link during every boot ... which in turn would require write acces to /etc/init.d, but that's currently not possible on the desire.
